Here are the top races most likely to flip parties, categorized and ranked from most to least likely. Colorado (Republican-held): Sen. Cory Gardner (R) is trying to pull away from Trump in this purple-blue state. Maine was never a state Trump was expected to win, so Collins always needed to get the votes of some Biden supporters. That’s likely why Collins wasted no time saying she opposes her party’s push to confirm a justice before the election. North Carolina (Republican-held): This swing state at nearly all levels of government has also been trending Democrats’ way, including the Senate race.
